4hw.com.cn: in recent years, people have paid more and more attention to the air problem. For the sake of family health, many families have installed air purifiers. However, there are not only air purifiers but also fresh air systems for air purification. What is the fresh air system? What is the difference between fresh air system and central air conditioning? Let's have a look.
What is the fresh air system
The fresh air system is an air treatment system composed of air supply system and exhaust system. It is divided into two types: the pipeline fresh air system and the non pipeline fresh air system. The air introduced to the outdoor can be purified by the fresh air fan, and the indoor air can be discharged through the pipeline. The pipeline fresh air system is more suitable for industrial or large-area office area because of the large work volume, and the fresh air system without pipeline is more suitable for small-area family use.
Difference between central air conditioning and fresh air system
The fresh air system is mainly responsible for ventilation in the room, while the central air conditioning is responsible for room temperature regulation. This is the biggest difference between the two. The fresh air system can't keep warm, and the central air conditioning's filtering air effect is not very good. The fresh air system and the central air conditioning are the same household equipment, and they are complementary in improving the living comfort. Fresh air and proper temperature will make people feel very comfortable.
Is it necessary to install central air conditioning and fresh air system at the same time
It can be installed at the same time. The domestic fresh air system and the central air conditioning can work together, which can reduce the loss of the machine and extend the service life of the equipment. For example: the outdoor temperature is high in summer. When entering the room through the "total heat exchanger" of the fresh air system, the total heat exchange rate is close to 80%, which will greatly reduce the temperature of the fresh air, so that the central air conditioning does not need too much energy consumption to reduce the temperature. In winter, the fresh air can also enter the room through heat exchange, so that the temperature will also be higher than the outdoor temperature, so as to reduce the loss of air conditioning and heating, which can save energy consumption of air conditioning.
